My system equipped with i7 and gtx 1070 and for some reason the slider has no effect on the brightness. I tried many solution but no fix, xbacklight, editing grub quiet splash video.use_native_backlight=1 acpi_backlight=vendor
and https://bugs.launchpad.net/ubuntu/+s...19/comments/30

but non of these solution help, I don't know what to do or how to proceed on fixing this issue, any help would be great thanks

You might find this interesting https://www.linuxquestions.org/quest...ad-4175614092/

However if you wish to continue, check out xrandr with the --brightness option run xrandr --help for more info.

Simple: DO NOT USE KALI. Their own website says specifically it's for advanced Linux users, and even then only for network security/pentesting. NOT to be used as a daily-use distro or main desktop. There is no reason, at all, to use it otherwise. Anything you can do with Kali, can be done with any other distro of Linux. Load Mint or Ubuntu, and everything will probably 'just work'.

Kali is a 'convenience' distro. It's well done, but all of the tweaks and security/pentesting tools are already loaded, which makes things easy for someone who needs such things. But there's no reason to use it otherwise. If you have a genuine need for it, load it on a thumbdrive, and use it from there as needed.

but anyways this contribute nothing to the fix of brightness issue. Is still linux so there's nothing advance or professional about it, you are making it sound like rocket science

You are missing the point entirely. Kali was NOT DESIGNED to do what you're after. While you can make it do so, it is AGAIN, designed for advanced Linux users. So if you are one, you should have no problems. You are using the wrong distro of Linux, and that is why you're having problems, period.

Your solution is to:

• Listen to the people who WROTE THE KALI DISTRO, and advise people to NOT use it like you're using it.
• Load Mint or Ubuntu, and have things work.

That's it. If you choose to use Kali, that means you're an advanced and experienced Linux user, who won't mind compiling their kernel and video-drivers by hand, just to enable a graphics feature that ALREADY EXISTS in most other Linux desktop distros. If you are such a user, you won't need help doing it. Mill J gave you advice about xrandr to dim the screen. You can try to add
..into the /etc/X11/xorg.conf.d/ nvidia.conf file you find in there, and that MIGHT help, but it may not as well. You can adjust it with xrandr or by changing the value in the "brightness" file you can find under /sys/class/backlight/asus <something>, but that's manual as well. The sliders and other things, AGAIN, are things that Kali just doesn't support well, because IT IS NOT DESIGNED for desktop use.
